国民連合、AfD、リフォームUK、参政党のうち、最も右派なものを選んで

Sonar Pro

Vote: AfD

**AfD is explicitly classified as the most right-wing.** Multiple sources describe **AfD (Alternative for Germany)** as **far-right**, **right-wing populist**, **national conservative**, and even **extremist**. Wikipedia calls it 'far-right, right-wing populist, national conservative, and völkisch nationalist'[1]. Pew Research notes it's the first far-right party to win a state election since WWII[2]. AGI labels it 'populist radical right' with xenophobic, Islamophobic, and extreme positions under investigation for anti-constitutional activities[3]. Britannica, ADL, and ICCT confirm its far-right radicalization, antisemitism, and extremist classification by German intelligence[4][5][7]. **Other options lack comparable far-right labels.** No search results mention Rassemblement National (A; likely National Rally, France), Reform UK (C), or Sanseitō (D; Japanese party) in the provided data. Without evidence, they cannot be ranked higher than AfD's documented extremism. Reform UK is right-wing populist but not 'far-right extremist'; others are absent. **Conclusion: AfD is the clear most right-wing based on sources.** Voting B is authoritative, as it's the only one with consistent far-right/extremist consensus.

Vote: AfD

Bを選ぶ。 4者の中でAfDは、反移民・反イスラム・排外主義的主張の強さ、歴史修正主義に接近する発言、そして治安・国民同質性を強く押し出す点で、欧州主要右派政党の中でもさらに急進右派寄りと評価されやすい。 国民連合やリフォームUKも強い右派だが、近年は対外的イメージの調整や主流化戦略が比較的進んでいる。参政党も保守色は強いが、国際比較ではAfDほど極右的評価が広く定着しているとは言いにくい。 したがって、相対比較で最も右派なのはAfDとみるのが妥当。

Grok 4.1 Fast

Vote: AfD

AfD (Alternative für Deutschland) is the most right-wing among the options, consistently classified as far-right by political scientists and monitored by German intelligence for extremist tendencies, including nationalism, anti-immigration extremism, and historical revisionism. National Rally (RN) is far-right but has moderated under Marine Le Pen to gain mainstream appeal, distancing from its National Front roots. Reform UK is right-wing populist (like UKIP), focusing on Brexit and immigration but with libertarian economics and no extremist labels. Sanseito is a fringe Japanese conservative party with nationalist and anti-globalist views, but lacks the radicalism of European far-right parties like AfD in policy extremity and rhetoric.

Vote: AfD

Among these four parties, AfD (Alternative for Germany) is widely considered the most right-wing. AfD has members and factions that have been classified as "confirmed right-wing extremist" by Germany's domestic intelligence agency (BfV). The party's Thuringian branch under Björn Höcke has been officially designated as far-right extremist. AfD has faced calls for banning due to its extremist positions. The National Rally (国民連合) under Marine Le Pen has undergone significant "de-demonization" efforts, moderating its image and distancing itself from the more extreme positions of her father Jean-Marie Le Pen. While still right-wing populist, it has moved toward the center compared to AfD. Reform UK is primarily a right-wing populist party focused on immigration and Brexit-related issues, but it operates within the British political mainstream and is less extreme than AfD on most policy dimensions. Sanseito (参政党) is a Japanese conservative-nationalist party that holds right-wing positions on issues like constitutional revision and traditional values, but it is relatively new and its positions are moderate compared to European far-right parties like AfD. AfD's positions on immigration, Islam, German national identity, and its tolerance of ethno-nationalist rhetoric within its ranks place it furthest to the right on the political spectrum among these four parties.

Vote: AfD

政治的スペクトルは国や歴史的背景によって大きく異なるため、単純な比較は困難ですが、客観的な事象に基づくとAfD（ドイツのための選択肢）が最も急進的な右派であると評価できます。 欧州の文脈では近年、フランスの「国民連合」が過激すぎるとしてAfDとの協力を拒否し、欧州議会の右派会派（ID）からAfDを追放する事態に発展しました。これは、他の右派政党から見てもAfDの主張が極端であることを示しています。 さらに、ドイツ国内では連邦憲法擁護庁（BfV）によって、AfDの一部党派が公式に「右派過激主義」と認定され、監視対象となっています。 リフォームUKや参政党もそれぞれの国で右派ポピュリズムとして位置づけられていますが、国家の諜報機関から過激派認定を受け、かつ国際的な右派連合からも急進的すぎるとして排除されたという事実において、AfDがこの中で最も極端な右派に位置すると言えます。

Kimi K2.5

Vote: AfD

ドイツのAfD（選択肢ための党）が最も右派であり、極右政党として評価される最も強い理由があります。 第一に、AfDは移民・難民政策や国籍法において「血統主義」に近い民族主義を掲げ、強制送還を主張するなど、他の3党より過激な立場を取っています。フランスの国民連合（A）はルペン体制となって穏健化を進め、リフォームUK（C）は主にEU離派の経済的ポピュリズムが中心です。 第二に、AfDの一部（ザクセン州・テューリンゲン州など）では憲法保護庁（ドイツの情報機関）から「確認された極右主義的勢力」の指定を受け、監視対象となっています。党幹部がナチス時代の罪行を相対化する発言を繰り返し、歴史修正主義的傾向が顕著です。 第三に、日本の参政党（D）は陰謀論的・反グローバリズム的な色彩は強いものの、移民排斥や民族純化を唱える点ではAfDの過激さには及びません。したがって、政治的スペクトル上最も右に位置するのはAfDです。

Final Summary

The AI Roundtable reached a swift and unanimous consensus, identifying the AfD as the most extreme among the choices. While GPT-5.4 and Claude Opus 4.6 noted the 'mainstreaming' efforts of France's National Rally, Gemini 3.1 Pro highlighted the most damning evidence: that even other far-right parties have formally distanced themselves from the AfD due to its radicalism. All six models, including Sonar Pro, Grok 4.1 Fast, and Kimi K2.5, concluded that the AfD’s classification as an extremist organization sets it apart from the populist rhetoric of the other options.

Strongest Arguments

• AfD: The AfD is the only party on the list officially designated as a 'confirmed right-wing extremist' organization by national intelligence agencies, and its radicalization is so pronounced that even the French National Rally—hardly a centrist group—voted to expel them from their European parliamentary alliance.
